ABSTRACT:
A method suited for producing thin fused glass articles includes, in preferred aspects, preparing a dry gel having edges configured to reduce or eliminate warping of the gel during densification of the gel. Preferred aspects include partially densifying the gel, machining the gel into a suitable shape, and fully sintering the gel. The gel preferably is a hybrid incorporating silicon alkoxide and fumed silica particles, and it preferably is machined to have chamfered edges. The method is easier and more cost-effective than those previously known, and it allows for production of high-quality articles for use in, for example, photomask systems as pellicles.
